Jeremy is having a tough time in prison, he is a marked man

Family friend

He has been forced to sign the Sex Offenders’ Register and been banned from working with children for life.

The nine months he spent on remand before his trial at Lewes Crown Court saw a frantic exchange of correspondence between the love-struck pair.

But the contact ban means Forrest cannot reply to the numerous love letters sent by the girl, a pupil in his maths class at Bishop Bell Church of England School in Eastbourne, East Sussex.

The Daily Express can reveal bosses at tough Lewes Prison, where London gangster Reggie Kray was once held, are mulling whether to intercept her mail to prevent it getting to Forrest.

Despite using his talent to teach illiterate inmates to read and write, Forrest has become a “marked man” inside after confessing to a string of child sex offences just seconds before he was sentenced for child abduction.

A worried family friend told how he had endured a “rough time” after his court appearance but the prospect of seeing and hearing from his child lover were what got him through each day.
